Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If chemical fungicides are used to combat plant pathogens, then pathogen control effectiveness is improved, but health problems and pesticide resistance develop
Solution Approach 1:
The patent replaces chemical fungicides with a biological system using Trichoderma viride fungus and its metabolites to control plant pathogens. The formulation uses natural biological mechanisms (antibiosis, mycoparasitism, induction of systemic resistance) instead of chemical mechanisms, thereby maintaining pathogen control effectiveness while eliminating health problems and resistance issues associated with chemical fungicides.
Solution Approach 2:
The patent introduces Trichoderma viride filtrate and its metabolites as intermediary substances that mediate between the plant and pathogen interaction. These biological intermediaries produce antifungal compounds and stimulate plant defense mechanisms, providing an alternative to direct chemical fungicide application while achieving pathogen control.
2Object-affected harmful factors
If microorganisms are used for biocontrol, then health safety is improved, but vitality and activity are lost over time
Solution Approach 1:
The patent extracts the active metabolites and filtrate from the Trichoderma viride fungus, separating the beneficial biological activity from the living organism itself. This extraction allows the active components (antibiotics, enzymes, growth regulators) to be formulated in a stable form that retains biological activity and health safety benefits without the limitations of live microorganism storage and viability.
Solution Approach 2:
The patent changes the physical and chemical parameters of the biocontrol agent by using filtrate and metabolites instead of whole living fungi. This parameter change transforms the product into a stable formulation that can be stored and applied effectively, maintaining biological activity while improving shelf life and ease of use compared to live microorganism-based products.
3Reliability
If biocontrol formulations are used, then pathogen resistance is avoided, but stability during storage is reduced
Solution Approach 1:
The patent creates a composite formulation combining Trichoderma viride filtrate with inert carriers and stabilizing agents. This composite structure protects the sensitive biological metabolites during storage while maintaining their biocontrol activity. The formulation integrates multiple components (filtrate, carriers, adjuvants) that work together to enhance both storage stability and pathogen control effectiveness.
Solution Approach 2:
The patent uses a formulation approach that prioritizes effective delivery of biocontrol agents over long-term stability of the entire product. The formulation is designed for optimal performance during the application window, using stable inert carriers and protective agents that maintain adequate stability during storage and application without requiring the entire formulation to be highly stable over extended periods.
